Cutting mechanism for paper tubes

Abstract

The invention relates to a cutting mechanism for paper tubes. The cutting mechanism is used for cutting the wound paper tubes in a tube winding machine into sections, and the paper tubes are conveyed through a conveying device. The cutting mechanism for the paper tubes comprises a cutting device, a driving device and a sensing device which are arranged sequentially in a conveying direction of the paper tube, wherein the driving device is used for driving the cutting device to move synchronously with the paper tubes in the conveying direction of the paper tubes; the sensing device is electrically connected with the driving device and the cutting device and produces control signals to be transmitted to the driving device and the cutting device; and the cutting device comprises a base, a first cutting device and a second cutting device, the base is horizontally arranged below the paper tape, and the first cutting device and the second cutting device are arranged on the base and located on two sides of each paper tube. According to the cutting mechanism for the paper tubes, the first cutting device and the second cutting device are arranged on two sides of a core roller for synchronous cutting, so that the cutting efficiency is improved greatly; and at the same time, the sensing device adopting a simple structure is arranged, so that the driving device and the cutting device can be well controlled, the lengths of the cut paper tubes are guaranteed to be equal, and notches are parallel and level.

Description

technical field [0001] The invention relates to a paper tube cutting mechanism in a tube rolling machine. Background technique [0002] After the paper tube in the tube coiling machine is wound, it needs to be cut into sections for easy processing. In the prior art, the cutting mechanism is often only installed on one side of the core roller, and the cutting efficiency is low. At the same time, it is difficult to control the length of the paper tube after being cut into sections. Some cutting effects are good but the structure is too complicated. , Although some are simple in structure, they often cannot control the cutting length of the paper tube well. Contents of the invention [0003] The purpose of the present invention is to provide a paper tube cutting mechanism with simple structure and good cutting effect. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A paper tube cutting mechanism, which is us...
